Abstract
The role of inflammation has been proven in acute myocardial infarction (AMI) pathogenesis. Due to the effect of NLRP3 gene expression in the inflammation process of MI, we aimed to explore the expression changes and diagnostic power of four inflammation-related miRNAs including miR-17-3p, miR-101-3p, miR-335-3p, miR-296-3p and their potential target, NLRP3, in ST-segment elevation myocardial infarction (STEMI), and non-STEMI (NSTEMI) patients as two major classes of AMI. The expression level of these genes were evaluated in 300 participants equally divided into three groups of STEMI, NSTEMI, and control using quantitative real-time PCR. The expression level of NLRP3 was upregulated in STEMI and NSTEMI patients compared to control subjects. Besides, the expression levels of miR-17-3p, miR-101-3p, and miR-296-3p were significantly downregulated in STEMI and NSTEMI patients compared to controls. The increased expression of NLRP3 had a very strong inverse correlation with miR-17-3p in patients with STEMI and with miR-101-3p in the STEMI and NSTEMI patients. ROC curve analysis showed that the expression level of miR-17-3p had the highest diagnostic power for discrimination between STEMI patients and controls. Remarkably, the combination of all markers resulted in a higher AUC. In summary, there is a significant association between the expression levels of miR-17-3p, miR-101-3p, miR-335-3p, miR-296-3p, and NLRP3 and the incidence of AMI. Although the miR-17-3p expression level has the highest diagnostic power to distinguish between STEMI patients and control subjects, the combination of these miRNAs and NLRP3 could serve as a novel potential diagnostic biomarker of STEMI.

Abstract
The objectives of the study were to (i) document refugee, immigrant and migrant (RIM) communities' knowledge, attitudes and beliefs (KABs) related to the Coronavirus disease (COVID-19) vaccine and (ii) identify best practices for developing and disseminating culturally and linguistically responsive health messaging addressing those KABs. Thirteen online focus groups (OFGs) in 10 languages were conducted. Each OFG was conducted in the participants' native language. OFGs were recorded, transcribed, translated and uploaded to qualitative software for coding. A thematic analysis was conducted. Results suggest that while there was some variation between different language groups (e.g. whether religious leaders were seen as trusted sources of information about COVID), there were also important commonalities. Most language groups (i) alluded to hearing about or having gaps in knowledge about COVID-19/the COVID-19 vaccine, (ii) reported hearing negative or conflicting stories about the vaccine and (iii) shared concerns about the negative side effects of the vaccine. There continues to be a need for health messaging in RIM communities that is culturally and linguistically concordant and follows health literacy guidelines. Message content about the COVID-19 vaccine should focus on vaccine importance, effectiveness and safety, should be multimodal and should be primarily delivered by healthcare professionals and community members who have already been vaccinated.

Abstract
BACKGROUND Previous studies evaluated the impact of particle matters (PM) on the risk of acute myocardial infarction (AMI) based on local registries. HYPOTHESIS This study aimed to evaluate possible short term effect of air pollutants on occurrence of AMI based on a specific case report sheet that was designed for this purpose. METHODS AMI was documented among 982 patients who referred to the emergency departments in Tehran, Iran, between July 2017 to March 2019. For each patient, case period was defined as 24 hour period preceding the time of emergency admission and referent periods were defined as the corresponding time in 1, 2, and 3 weeks before the admission. The associations of particulate matter with an aerodynamic diameter ≤2.5 μm (PM2 .5 ) and particulate matter with an aerodynamic diameter ≤10 μm (PM10 ) with AMI were analyzed using conditional logistic regression in a case-crossover design. RESULT Increase in PM2.5 and PM10 was significantly associated with the occurrence of AMI with and without adjustment for the temperature and humidity. In the adjusted model each 10 μg/m3 increase of PM10 and PM2.5 in case periods was significantly associated with increase myocardial infarction events (95% CI = 1.041-1.099, OR = 1.069 and 95% CI = 1.073-1.196, and OR = 1.133, respectively). Subgroup analysis showed that increase in PM10 did not increase AMI events in diabetic subgroup, but in all other subgroups PM10 and PM2 .5 concentration showed positive associations with increased AMI events. CONCLUSION Acute exposure to ambient air pollution was associated with increased risk of AMI irrespective of temperature and humidity.

Abstract
Purpose of Review
This article reviews all the most common therapeutic strategies of prostate cancer, systemic or local, and all the following morpho-structural alterations, with the aim of helping the radiologist to recognize the signs of recurrence by using mp-MRI.
Recent Findings
According to the most recent evidences, prostate mp-MRI has now become a strong, non-invasive, and valid tool to evaluate all patient treated for prostatic carcinoma across the time, especially in the suspicion of biochemical recurrence.
Summary
The minimal signs of focal recurrence can put a strain on radiologists, especially if they are novice with multi-parametric prostate MRI. Familiarizing themselves with the outcomes of treatment, local or systemic, and its characteristics to MR imaging is indispensable to avoid diagnostic pitfalls and, subsequently, unnecessary reinterventions.

Abstract
INTRODUCTION ST-elevation myocardial infarction (STEMI) is known to be associated with significant arrhythmia and consequent mortality. QT prolongation is a risk factor for arrhythmia in STEMI patients who underwent primary percutaneous coronary intervention (PPCI). The aim of this investigation was to evaluate the association of corrected QT interval (QTc), QT dispersion (QTd), T-wave peak to end (TPE), and fragmented QRS with mortality in these patients. METHODS Eligible patients with the characteristic symptoms of STEMI who underwent PPCI were included. QTc, QTd, TPE, and fragmented QRS were measured before and after the PPCI. These predictors were compared between patients who died during hospitalization and discharged patients. RESULTS After coronary angiography, 10 patients (4%) died during the hospitalization after PPCI. Comparing the non-survivers and discharged patients in terms of arrhythmia predictors showed that the mean QT dispersion and TPE before intervention were significantly higher in the non-survivors. Also, the number of patients who experienced fragmented QRS both before and after the intervention was significantly higher in the non-survivors. CONCLUSION These data suggested that evaluating such arrhythmia predictors, especially before PPCI, could be used as a predictor of mortality in STEMI patients who underwent PPCI.

Abstract
BACKGROUND The Primary Percutaneous Coronary Intervention (PPCI) is the preferred therapeutic strategy for patients who experienced ST-Elevation Myocardial Infarction (STEMI). OBJECTIVE We aimed to evaluate the association of hematological indices, including hemoglobin level, platelets, White Blood Cells (WBCs) count, and MPV before PPCI with the TIMI grade flow after PPCI. METHODS STEMI patients who experienced PPCI were included in the present retrospective crosssectional study. Then participants were divided into three groups based on their post-procedural TIMI flow grades. Demographic data and hematologic indices of patients before PPCI were collected and their association with the TIMI grade flow after PPCI was evaluated. To compare the quantitative and qualitative variables, chi-square and t-tests were performed, respectively. RESULTS We found that elevated levels of hemoglobin and decreased levels of MPV had a significant association with an advanced grade of TIMI flow. Interestingly, in the normal range, there was a significant association between higher platelet count and TIMI-flow grade 1. Besides, TIMI flow grades 2 and 3 had a significant association with low and moderate platelets count, respectively. CONCLUSION In conclusion, evaluating MPV, platelets, and hemoglobin levels before PPCI as easy and accessible parameters may be able to identify high-risk STEMI patients undergoing PPCI.

Abstract
Cardiovascular wellbeing has been dramatically affected by severe acute respiratory syndrome coronavirus (SARS-CoV-2), the reason for the coronavirus disease pandemic 2019 (COVID-19) pandemic. There is a greater risk of morbidity and death in individuals with preexisting heart diseases. Clinical syndromes of the acute coronary syndrome, acute myocardial injury, myocarditis, arrhythmias, heart failure, and venous thromboembolism can, directly and indirectly, affect the heart. There may also be adverse heart effects of specific therapeutics under review for COVID-19. The renin-angiotensin-aldosterone system (RAAS) mechanism in virus replication makes it essential to understand the consequences of the system-modulating medications. For optimum patient care, detailed knowledge of specific cardiovascular symptoms of COVID-19 and the role of RAAS in the prognosis of COVID-19 disease is necessary.

Abstract
Background: The coronary no-reflow phenomenon is an adverse complication of percutaneous coronary interventions (PCI) which significantly worsens the outcome and survival. In this study, we have evaluated the correlation of no-reflow phenomenon with demographic, biochemical and anatomical factors. Methods: We included 306 patients (193 male) with acute ST-elevation myocardial infarction (STEMI) who undergone primary PCI in our center. Demographic factors, as well as biochemistry test results were obtained. Also, the Thrombolysis in Myocardial Infarction (TIMI) grade and TIMI frame count (TFC) was measured. The correlation of no-reflow phenomenon with demographic, biochemical and anatomical factors was analyzed. Results: Patients with a mean age of 56.41 ± 11.8 years were divided into two groups depending on the TIMI score (Group 1 or Normal flow and Group 2 or No-reflow). Symptom-to-procedure time, door-to-procedure time, serum creatinine level, hs-CRP level, and Neutrophil to Lymphocyte Ratio (NLR) were significantly higher among group 2. TFC had negative significant correlation with male gender, and positive significant correlation with age, diabetes mellitus, hs-CRP level, WBC count, and NLR. Age of more than 62.5 years and serum creatinine level of more than 0.89 mg/dL can optimally predict the no reflow phenomena. Conclusions: According to our results, it seems that female gender, older ages, DM, multi-vessel involvement, delayed reperfusion, and increased NLR can predict the risk of no-reflow after primary PCI in the setting of Acute Myocardial Infarction.

Abstract
Background: The decrease in fractional flow reserve (FFR) after adenosine administration from baseline FFR value (termed as ΔFFR) may reflect the compensatory capacity of the microvascular circulation and thus may predict significant coronary stenotic lesions. We aimed to investigate whether baseline FFR and ΔFFR can help identify the coronary ischemic lesion and its severity. Materials and Methods: This cross-sectional study was performed on 154 consecutive patients (Mean age 62.42 ± 9.36 years) that underwent coronary angiography and with definitive intermediate coronary lesions at any of the coronary vessels. FFR was calculated by dividing the mean distal intracoronary pressure by the mean arterial pressure. ΔFFR was also defined as the difference between baseline FFR and hyperemic FFR (considering FFR<0.75 as the criteria for ischemia). Results: The area under receiver-operating characteristic curve for baseline FFR was found as 0.933, and for ΔFFR was 0.946 indicated high values of both indices for predicting ischemic lesions. The best cut-off point for baseline FFR and ΔFFR for discriminating ischemic lesions from the normal condition was 89.5 (yielding a sensitivity of 92.2% and a specificity of 68.0%) and 9.5 (yielding a sensitivity of 96.0% and a specificity of 85.3%), respectively. Conclusion: Our study could successfully demonstrate the high value of both baseline FFR and ΔFFR for predicting coronary ischemic lesions with the cut-off values of <89.5 and >9.5, respectively.

Abstract
OBJECTIVES In this study, we aimed to assess the value of admission time CBC parameters in predicting post-primary PCI corrected TIMI frame count. BACKGROUND Recent years have witnessed a large series of studies evaluating different laboratory variables to predict no-reflow phenomenon following primary PCI (PPCI) in patients with STEMI. However, a general agreement about the most reliable predictor of the no-reflow phenomenon is challenging and also intriguing. METHODS The current study concluded 208 consecutive patients who underwent primary PCI for ST-Elevation Myocardial Infarction (STEMI) from January 2014 to February 2016. Blood samples were obtained after taking ECG. Complete blood samples were collected and analyzed within 5 minutes from sampling. Post-PCI corrected Thrombolysis in Myocardial Infarction (TIMI) frame count was determined by one interventional cardiologist blinded to patients' clinical data. The correlation between admission time blood parameters and post-primary PCI corrected TIMI frame count in patients with STEMI were assessed. RESULTS Corrected TIMI frame count was positively correlated with WBC count (R: 0.18, P-value: <0.01), neutrophil count (R: 0.34, P-value: <0.01), and platelet count (R: 0.23, P-value: <0.01) and negatively correlated with lymphocyte count (R: -0.2, P-value: <0.01). Multiple linear regression results demonstrated that corrected TIMI frame count was positively correlated with neutrophil count (P < 0·001) and platelet count (P < 0·001) and negatively correlated with lymphocyte count (p=0.004). CONCLUSION High counts of WBC, neutrophil, and platelet and low count of lymphocyte may be predictors of no-reflow in STEMI patients undergoing PPCI. The clinical significance of such predictive parameters becomes clear as we consider the treatment approach in STEMI patients. Appropriate risk stratification leads to better treatment planning and allocation of resources.

Abstract
Marijuana is a widely used illicit substance among young adults and its abuse has been reported worldwide. Marijuana is a rare trigger of acute myocardial infarction and acute pancreatitis. We present a 25-year-old man with acute pancreatitis subsequently complicated by acute ST-elevation myocardial infarction (STEMI), which was associated with marijuana abuse. This case highlights the need and importance of awareness among public about this rare but potentially lethal adverse effect. Also, it draws attention when clinicians confront patients with history of substance abuse, they should be alert to the possibility of concurrent occurrence of serious medical conditions that may be adverse effects of substance use. Acute pancreatitis with concurrent acute STEMI is a rare situation but is a challenge for many emergency physicians, and it can lead to trouble outcomes if it not be quickly diagnosed and properly managed. We demonstrate successful management in this complicated patient with primary angioplasty.

Abstract
Background: The use of phenotypic parameters along with other noninvasive diagnostic modality can lead to early diagnosis of coronary artery disease (CAD) and prevent its life-threatening outcome. Recently, the application of head and face components for assessing the risk for CAD much attention has been paid. The present study aimed to assess the relationship between ear characteristics (transverse groove on the earlobe and hair growth on the ear) and the risk for CAD and its severity among Iranian patients. Materials and Methods: In this cross-sectional study, the study population consisted of 105 consecutive patients with suspected CAD undergoing coronary angiography. The severity of CAD was determined by the number of disease vessels as well as the presence of left main lesions assessed by coronary angiography. All patients were examined to evaluate the appearance of ear regarding the presence of transverse groove on the earlobe and hair growth on the ear. Results: Comparing cardiovascular parameters across the groups with and without transverse groove on the earlobe showed a higher rate of CAD as well as the higher number of involved coronary arteries than in the groups without transverse groove on the earlobe. Similarly, the presence of CAD and its higher severity were more revealed in patients with hair growth on the ear as compared to the group without this phenotype. According to multivariable logistic regression analysis and with the presence of baseline parameters, the presence of transverse groove on the earlobe and hair growth on the ear increased the risk for CAD by 2.4 and 4.4 fold, respectively. Conclusion: Along with classic cardiovascular risk factors, the role of growing hair on the ear and transverse groove on the ear to predict high risk for CAD should be considered.

Abstract
In this report, we describe a case of spontaneous coronary dissection involving left anterior descending artery presenting with acute anterior myocardial infarction successfully treated with thrombolytic and conservative therapy with a suggestion that spontaneous resolution of thrombus occurred before coronary intervention could be performed. As we did not have initial angiogram due to patient's refusal, this assumption is speculative. However, this case suggests that dissections may heal spontaneously and could be treated with conservative approach in selected cases based on best clinical judgment. It is important to realize that the clinical course of a major coronary artery dissection remains unpredictable. Therefore, cardiologists should always treat each case individually and consider coronary interventions if conservative treatment is not leading to resolution of ST elevation or in patients with hemodynamic compromise. This case is followed by discussion about conservative versus invasive management of spontaneous coronary dissections.

Abstract
BACKGROUND Obstruction of the access vein following cardiac pacemaker and defibrillator implantation is a common complication. However, the exact incidence and contributing risk factors are unknown. The aim of this study is to determine the incidence and analyze the contribution of each risk factor. METHODS 57 consecutive patients candidate for their first transvenous pacemaker, implantable cardioverter-defibrillator (ICD), or cardiac resynchronization therapy device implantation were enrolled. After implantation, venography of the ipsilateral peripheral arm was performed. Patients underwent their second venography after the follow-up period of 3 to 6 months. RESULTS 42 patients (13 females, mean age 59.71 ± 12.33) completed the study. The followup venography showed significant venous obstruction (more than 50%) in 9 (21%) patients, but in none of the individuals, venography revealed total occlusion of the veins. Patients with obstruction had more leads in their veins (2.56 ± 0.53 vs 1.58 ± 0.71, P = 0.001). Venous obstruction was significantly more prevalent in patients with implanted cardiac resynchronization therapy device compared with an ICD or pacemaker (p = 0. 01). Age, gender, diabetes mellitus, hypertension, ischemic heart disease and antiplatelet consumption did not reveal any other contribution to the risk of thrombosis. In multivariate analysis, total lead number was a positive predictor for venous occlusion (P = 0.015, OR:19.2, and CI: 1.7-207.1). CONCLUSION Venous obstruction is relatively frequent after pacemaker or ICD implantation. This study also shows that pacemaker and ICD leads have a similar risk for lead-related venous obstruction. However, patients with multiple leads are associated with an increased risk.

Abstract
We present a 33-year-old man with atypical chest pain and with no significant past medical history. The patient was finally diagnosed as a case of huge fistula from the left main coronary artery to the right atrium, a very rare condition with challenging diagnostic and therapeutic approaches. The majority of cases of coronary artery fistula are small, asymptomatic and clinically undetectable; they frequently do not cause any complications and can spontaneously resolve. However, larger fistulas are frequently three times the size of a typical caliber of a coronary artery and may or may not cause symptoms or complications.

Abstract
We found a coexistence of Mahaim fibers, coarctation of aorta and bicuspid valve in a young patient presenting with palpitations and subraventricular tachycardia. This rare combination of these three congenital cardiac abnormalities occurring in the same patient has not been reported previously. Detailed cardiac studies unmasked the patient's cardiac abnormalities. Furthermore, successful percutaneous intervention in treating coarctation and catheter-based ablation of Mahaim fibers were performed with resolution of symptoms. This case is discussed here in detail, alongside a review of the literature.

Abstract
Background and Aim: Applying fractional flow reserve (FFR) recently helped to assess borderline coronary defects and also facilitates assessment of these lesions. The present study aimed to assess cost-effectiveness of FFR in detection of these borderline lesions. Methods: This cross-sectional study was conducted on140 consecutive patients with 219 diseased arteries who underwent coronary angiography and suffered intermediate coronary lesions. Results: Of 18 patients who candidate for CABG before FFR, only one patient underwent CABG after determining FFR (P-value<0.05), while 15 patients were scheduled for PCI and 2 patients for medical treatment. Of 122 patients who candidate for PCI, 59 were programmed to underwent PCI after FFR determination (P-value<0.05), while the strategy in 63 patients (47 with one-vessel disease, 15 with two vessel diseases, and 1 with three vessel diseases) was modified to medical treatment. Considering strategy modifying from PCI to medical treatment, 101 stents were saved (P-value<0.05). Also, in change of strategy from CABG to PCI, spending has decreased as much as 77.3% (P-value<0.05). Furthermore, the change of treatment approach from PCI on much number of coronary vessels to PCI on less number of coronary lesions led to saving of 52.2% of costs (P-value<0.05). Conclusions:In patients with an intermediate coronary lesion, measuring FFR to guide the decision to determine treatment strategy may lead to significant cost savings. (www.actabiomedica.it)

Abstract
BACKGROUND Implantable cardioverter-defibrillator (ICD) is the most effective therapy currently available to prevent sudden cardiac death (SCD) in patients with left ventricular (LV) dysfunction. Although LV ejection fraction (LVEF) is an excellent marker of SCD in these patients, determining other predictors might help to identify patients who will be benefit more from device implantation. The purpose of this study was to determine whether abnormal LV sphericity index (SI) in transthoracic echocardiography is associated with appropriate ICD therapy in these patients. METHODS A total of 140 patients with primary ICD implantation (mean age 62.59 ± 11.36 years; 98 [70%] male) were included. The patients were classified into "no ICD therapy" or "ICD therapy" group according to the information of their devices for a maximum of 2 previous years. In four-chamber view image of transthoracic echocardiography, SI was calculated by dividing the major-axis dimension to minor-axis dimension of LV in both groups. RESULTS Compared with patients with no ICD therapy, patients in ICD therapy group had lower LVEF (31.36 ± 9.58 vs 23.24 ± 6.03, P = 0.0001) and lower SI (1.79 ± 0.29 vs 1.57 ± 0.32, P = 0.0001). In multivariant logistic regression analysis, the SI of ≤1.58 was associated with fourfold increase of appropriate ICD therapy, even after adjusting for LVEF (odds ratio, 4.08; 95% confidence interval, 1.71-9.75; P = 0.02). CONCLUSION Simple echocardiographic sphericity dimension index as a marker of cardiac remodeling may be an important predictor of appropriate ICD therapy in patients with primary prevention ICDs and may provide additive risk stratification in patients with LV systolic dysfunction.

Abstract
Background: Although metformin is not directly nephrotoxic, it has been postulated that it can impair gluconeogenesis from lactate, which may lead lactate to be accumulated under circumstances such as contrast-induced nephropathy. The present study aims to assess the role of metformin in lactate production in a group of diabetic patients with GFR > 60 ml/min per 1.73 m2undergoing coronary angiography. Methods: In the present randomized clinical trial, 162 metformin-treated diabetic patients were enrolled. The enlisted patients were scheduled to undergo coronary angiography at Modarres Hospital from Feb 2012 to Nov 2012. Patients were randomly allocated to continue metformin during peri-angiography period (M (+) group) or to stop the medication 24 hours prior the procedure (M (-) group). All the patients had glomerular filtration rate of >60 mL/min per 1.73 m2. Iodixanol was the only contrast media which in all patients. Metformin-associated lactic acidosis (MALA) was defined as an arterial pH <7.35 and plasma lactate concentration >5 mmol/L. Results:162 patients, including79 (48.7%) male and 83 (51.3%) female patients were enrolled in the study. The average of GFR was comparable in both groups (76 ml/min per 1.73 m2in the M (+) group versus 79 ml/min per 1.73 m2in the M (-) group, p=0.53). No significant difference was observed in the mean dose of metformin before the study between the 2 groups (2.18 tablets per day in M (+) group vs. 2.21 tablets per day in M(-) group, p=0.62).No lactic acidosis was observed in the studied groups. Conclusion: In conclusion, the results of the present study indicate that metformin continuation in diabetic patients with a GFR of more than 60 ml/min per 1.73 m2 undergoing coronary angiography does not enhance the risk of MALA development.

Abstract
BACKGROUND Unfavorable associations between air pollution and myocardial infarction are broadly investigated in recent studies and some of them revealed considerable associations; however, controversies exists between these investigations with regard to culprit components of air pollution and significance of correlation between myocardial infarction risk and air pollution. METHODS The association between exposure to PM10, PM2.5, ozone, carbon monoxide, sulfur dioxide, and nitrogen dioxide concentration of background air that residents of Tehran, the capital city of Iran, which is ranked as the most air polluted city of Iran and the relative risk of developing ST-elevation myocardial infarction (STEMI) were investigated by a case-crossover design. Our study included 208 patients admitted with a diagnosis of STEMI and undergone primary percutaneous intervention. Air pollutant concentration was averaged in 24-h windows preceding the time of onset of myocardial infarction for the case period. Besides, the mean level of each element of air pollution of the corresponding time in one week, two weeks and three weeks before onset of myocardial infarction, was averaged separately for each day as one control periods. Thus, 624 control periods were included in our investigation such that. Each patient is matched and compared with him/herself. RESULTS The mean level of PM10 in case periods (61.47µg/m3) was significantly higher than its level in control periods (57.86µg/m3) (P-value = 0.019, 95% CI: 1.002-1.018, RR = 1.010). Also, the mean level of PM2.5 in case periods (95.40µg/m3) was significantly higher than that in control days (90.88µg/m3) (P-value = 0.044, 95% CI: 1.001-1.011, RR = 1.006). The level of other components including NO2, SO2, CO and O3 showed no significant differences between case and control periods. A 10µg/m3 increase in PM10 and PM2.5 would result in 10.10% and 10.06% increase in STEMI event, respectively. Furthermore, the results of sub-group analysis showed that older patients (equal or more than 60 year-old), diabetic patients, non-hypertensive ones and patients with more than one diseased vessel may be more vulnerable to the harmful effect of particular matters including PM10 and PM2.5 on development of STEMI. CONCLUSION Air pollution is a worldwide pandemic with great potential to cause terrible events especially cardiovascular ones. PM2.5 and PM10 are amongst ambient air pollutant with a high risk of developing STEMI. Thus, more restrictive legislations should be applied to define a safe level of indoor and outdoor air pollutant production.

Abstract
AIMS To detect the significance of coronary artery disease in the patients, who are suspected, was assumed to be one of the advantages of 2D STE, as a novel non-invasive imaging modality with acceptable accuracy. METHODS In this study, 216 patients who were suspected to have coronary artery disease and candidate for coronary angiography, underwent rest two-dimensional speckle tracking echocardiography (2D STE) and negative global systolic longitudinal strain was evaluated. RESULTS Negative global systolic left ventricular longitudinal strain under 18% in rest 2D-STE was significantly prevalent in patients with significant CAD in coronary angiography (P value<0.0001).Our results revealed sensitivity of 91.1%, specificity of 63.0%, positive predictive value of 80.4%, negative predictive value of 81.0% and accuracy of 80.5% for rest 2D-STE in detection of significant CAD. CONCLUSION Here in we showed that rest Two-dimensional speckle tracking echocardiography could be a sensitive but nonspecific imaging modality to determine significant coronary artery disease. Future studies with large size will reveal more detailed findings.

Abstract
This study aimed to evaluate the effect of core shade and core and veneering thickness on color parameters and translucency of polyether ether ketone (PEEK). Sixty PEEK discs (0.5 and 1 mm in thickness) with white and dentine shades were veneered with A2 shade indirect composite resin with 0.5, 1 and 1.5 mm thickness (n=5). Cores without the veneering material served as controls for translucency evaluation. Color parameters were measured by a spectroradiometer. Color difference (ΔE₀₀) and translucency parameters (TP) were computed. Data were analyzed using one-way ANOVA and Tukey's test (for veneering thickness) and independent t-test (for core shade and thickness) via SPSS 20.0 (p⟨0.05). Regarding the veneering thickness, white cores of 0.5 mm thickness showed significant differences in all color parameters. In white cores of 1 mm thickness and dentine cores of 0.5 and 1 mm thickness, there were statistically significant differences only in L∗, a∗ and h∗. The mean TP was significantly higher in all white cores of 1 mm thickness than dentine cores of 1 mm. Considering ΔE₀₀=3.7 as clinically unacceptable, only three groups had higher mean ΔE₀₀ values. Core shade, core thickness, and the veneering thickness affected the color and translucency of PEEK restorations.

Abstract
BACKGROUND The change in the level of NT-pro-BNP (N-terminal-pro-Brain Natriuretic Peptide) is now considered as a reflection of the hemodynamic alterations and its circulatory reductions reported early after successful PTMC (percutaneous transvenous mitral commissurotomy). The present study aims to assess the change in the level of NT-pro BNP following PTMC in patients with mitral stenosis and also to determine the association between circulatory NT-pro-BNP reduction and post-PTMC echocardiography parameters. METHODS Twenty five symptomatic consecutive patients with severe MS undergoing elective PTMC were prospectively enrolled. All patients underwent echocardiography before and also 24 to 48 hours after PTMC. Peripheral blood samples were taken for measurement of NT-pro-BNP before as well as 24 to 48 hours after PTMC. The patients were also classified in group with normal sinus rhythm or having atrial fibrillation (AF) based on their 12-lead electrocardiogram. RESULTS It was shown a significant decrease in the parameters of PPG (Peak Pressure Gradient), MPG (Mean Pressure Gradient), PHT (Pressure Half Time), PAP (Pulmonary Arterial Pressure), LAV (Left Atrial Volume), and also a significant increase in MVA (Mitral Valve Area) RVS (Right Ventricular S velocity), and strains of lateral, septal, inferior and anterior walls of LA following PTMC. The mean LVEF remained unchanged after PTMC. The mean NT-pro-BNP before PTMC was 309.20 ± 17.97 pg/lit that significantly diminished after PTMC to 235.72 ± 22.46 pg/lit (p = 0.009). Among all echocardiography parameters, only MPG was positively associated with the change in NT-pro-BNP after PTMC. Comparing the change in echocardiography indices between the patients with normal rhythm and those with AF, lower change in PAP was shown in the group with AF. However, more change in the level of NT-pro-BNP after PTMC was shown in the patients with AF compared to those without this arrhythmia. CONCLUSION PTMC procedure leads to reduce the level of NT-pro-BNP. The change in NT-pro-BNP is an indicator for change in MS severity indicated by decreasing MPG parameter. Lower change in PAP as well as higher change in NT-pro-BNP is predicted following PTMC in the group with AF compared to those with normal sinus rhythm.

Abstract
BACKGROUND Ventriculophasic response (VR) refers to the shortening of the atrial cycle length (P-P-interval) that occurs during the heart block when a QRS complex is interposed between two P-waves. The aim of this study was to determine the factors affecting this phenomenon. METHODS Thirty patients with high grade heart block treated with dual chamber pacemaker were studied. The pacer function of the patients' device was temporarily programmed to the ventricular-inhibited mode at 30 pulses per minute. A total of 330 recordings containing two P-waves with an interposed QRS and its previous P-P interval without any QRS were collected. The VR was defined as being present when the P-P interval with an interposed QRS shortened more than 3% compared to the preceding P-P interval. RESULTS The VR was present in 45% of the recordings. In the multivariate logistic regression analysis, only a mid position of the interposed QRS was a positive predictor for presence of VR. However, there were no differences between recordings with or without VR groups according to QRS duration, paced or intrinsic interposed QRS. Hypertension and age had a negative correlation with the presence of VR when the QRS was interposed in the mid part. CONCLUSION We found that the VR was present in approximately half of our cases. This phenomenon was mostly affected by position of the interposed QRS according to the previous P-P interval.

Abstract
Abstract
Background. Recent studies have confirmed the essential and paramount role of the L-Citrulline on the nitric oxide regulation and the endothelial function improvement.
Materials and Methods. In this cross-over clinical trial, thirty patients, diagnosed with coronary artery disease (CAD) and flow mediated dilation to nitroglycerin dependent vasodilation (FMD/NMD) ratio less than 1, were included. The patients were randomly divided into two groups of 15 patients and underwent treatment by L-Citrulline or placebo for 15 days, in 2 step protocol. The indicators of assessment in the current study were the ratio of the FMD/NMD and FMD value.
Results. In the current cross-over clinical trial, the mean of FMD to NMD ratio and mean FMD value of all patients before starting the protocol were 0.91 ± 0.08 and 4.04 ± 0.51 mm, respectively. The final results of study showed that following L-Citrulline administration, mean FMD to NMD ratio and mean FMD value were enhanced to: 1.03 ± 0.09 and 4.96 ± 0.72 mm, respectively, which were statistically significant (P<0.001 and P<0.001, respectively). However, following placebo administration, mean FMD to NMD ratio and mean FMD value were receded to: 0.92 ± 0.09 and 4.06 ± 0.22 mm, respectively, which were not statistically significant (P = 0.75 and P = 0.89, respectively). Moreover, the improvement of mean FMD to NMD ratio (0.12 ± 0.02) and mean FMD value (0.92 ± 0.16 mm), following L-Citrulline administration, were statistically significant in comparison with the change of mean FMD to NMD ratio (0.01 ± 0.002) and mean FMD value (0.02 ± 0.003), following placebo administration (P<0.001 and P<0.001, respectively).
Conclusion. L-Citrulline treatment can lead to improvement of the endothelial function in patients diagnosed with CAD which are assessed via FMD to NMD ratio FMD value enhancements.

Abstract
BACKGROUND Inflammation has an important role in the development and progression of atherosclerosis, and acute phase proteins such as pentraxin-3 (PTX3) can be deployed in determining the prognosis of coronary artery disease (CAD). So the purpose of this paper was to evaluate the PTX3 level and its related factors in patients undergoing primary percutaneous coronary intervention (PCI). METHODS In this cross-sectional study, the PTX3 levels were determined for 100 patients with ST-elevation myocardial infarction referred to the Modarres Hospital, Tehran, Iran. Checklist included demographic data [age, gender, history of myocardial infarction (MI)] and characteristics of heart disease (type of MI, culprit, and pre-dilation). PTX3 was measured for all patients before PCI. RESULTS In this study, the mean age of the participants was 58.7 (11.4). Global registry of acute coronary events (GRACE) score was higher in the group with abnormal PTX3 levels (P = 0.008). The number of the involved vessels (P = 0.005), MI type (P = 0.05), and the need for PCI all had a significant relation with abnormal PTX3 levels. The increased levels of PTX3 received higher Killip class, lower ejection fraction, and higher GRACE score. The group with abnormal PTX3 had a significant difference in platelet counts (P = 0.018) in comparison with the group with normal level of PTX3. CONCLUSION Currently, the biomarkers are highly important in the field of cardiovascular diseases. The diagnostic and prognostic importance of PTX3 as a new marker has been underscored in recent studies. Differentiating between high-risk patients with acute cardiac infarction and low-risk ones through their clinical signs is difficult.

Abstract
Based on the complex spectral element method and the theory of fractional calculus, a hybrid complex damped spectral element method is developed. The new method is capable of making accurate predictions of the full dynamic behaviour of reinforced concrete cooling tower structures including soil-structure interaction effects. The dynamic soil-structure interaction of large space shell structures can be analysed using hybrid spectral-finite element method where the seismic wave propagation in the soil media has been modelled using the spectral element method. The frequency-dependent damping characteristic of soil materials can also be modelled accurately using the fractional derivative model. It is shown that the proposed method can be extended to develop a frequency domain dynamical method to analyse damped large space structures under earthquake excitation. The soil-structure dynamical solution is shown graphically, and the consistency of method is investigated. Using a computer program, the proposed formulation has been used to derive the dynamic response of a large concrete cooling tower with the soil media.

Abstract
Total occlusion of a coronary artery for more than 3 months is defined as chronic total occlusion (CTO). The goal of this study was to develop a risk score in predicting failure or success during attempted percutaneous coronary intervention (PCI) of CTO lesions using antegrade approach. This study was based on retrospective analyses of clinical and angiographic characteristics of CTO lesions that were assessed between February 2012 and February 2014. Success rate was defined as passing through occlusion with successful stent deployment using an antegrade approach. A total of 188 patients were studied. Mean ± SD age was 59 ± 9 years. Failure rate was 33%. In a stepwise multivariate regression analysis, bridging collaterals (OR = 6.7, CI = 1.97-23.17, score = 2), absence of stump (OR = 5.8, CI = 1.95-17.9, score = 2), presence of calcification (OR = 3.21, CI = 1.46-7.07, score = 1), presence of bending (OR = 2.8, CI = 1.28-6.10, score = 1), presence of near side branch (OR = 2.7, CI = 1.08-6.57, score = 1), and absence of retrograde filling (OR = 2.5, CI = 1.03-6.17, score = 1) were independent predictors of PCI failure. A score of 7 or more was associated with 100% failure rate whereas a score of 2 or less was associated with over 80% success rate. Most factors associated with failure of CTO-PCI are related to lesion characteristics. A new risk score (range 0-8) is developed to predict CTO-PCI success or failure rate during antegrade approach as a guide before attempting PCI of CTO lesions.

Abstract
INTRODUCTION The aim of this study was to investigate the efficacy and safety of intracoronary (IC) sodium nitroprusside infusion in comparison to IC adenosine for fractional flow reserve (FFR) measurement in moderately diseased coronary artery lesions for functional assessment. METHODS During a nine month period, a consecutive of 98 patients with suspected or known coronary artery disease with moderate stenosis found during angiography (40% to 70% stenosis), were enrolled in this study. Hyperemia was induced by bolus doses of IC adenosine followed by sodium nitroprusside for FFR measurement. RESULTS Both IC adenosine and IC sodium nitroprusside induced similar and significant reduction in FFR. There was no statistically difference in FFR values between adenosine vs sodium nitroprusside infusions (mean FFR 84.3±6.3 vs 85.7±6.2, p=0.1) respectively. Furthermore, comparing different FFR cut-off points between the groups (FFR<0.75, 0.75-0.8 and >0.8) showed no significant differences (p value=0.7). CONCLUSION An IC bolus of sodium nitroprusside (0.6μg/kg) infusion induces a similar degree of hyperemia to IC bolus of 100-300μg of adenosine. Therefore, IC sodium nitroprusside could be considered as an alternative drug to adenosine for FFR measurement with lower side effect profile.

Abstract
Hemorrhagic complications of thrombolytic therapy are rare but also serious and sometimes life-threatening. Liver hematoma is a very uncommon complication following thrombolytic therapy. We present a rare case of sub-capsular liver hematoma following streptokinase therapy of acute myocardial infarction as a challenging condition. This case report highlights that emergency physicians and cardiologists should be familiar with the significant and uncommon complications of thrombolytic agents, particularly streptokinase which is used generally in under- developed countries.

Abstract
Anatomical and functional mismatches are not uncommon in the assessment of coronary lesions. The aim of this study was to identify clinical and lesion-specific factors affecting angiographic, anatomical, and functional mismatch in intermediate coronary lesions. In patients who underwent coronary angiography for clinical reasons, fractional flow reserve (FFR), and quantitative coronary angiography (QCA) analyses for intermediate stenotic lesions were performed simultaneously. Mismatches between the measured values were analyzed. A total of 95 intermediate lesions were assessed simultaneously by visual angiography, FFR, and QCA. The visual-FFR mismatch was found in 40% of the lesions while reverse visual-FFR mismatch was determined in nearly 14% of the lesions. Mismatch and reverse mismatch between FFR and QCA parameters were observed in 10 and 23% of the lesions. FFR value was significant in 32% of the lesions while visually significant stenosis was shown in 61% of the lesions. Among the visual-FFR reverse mismatch group, the prevalence of culprit lesions within the left anterior descending (LAD) was significantly higher than other vessels (p value < 0.02). There were high frequencies of angiographic, QCA, and functional mismatches in analyses of intermediate coronary lesions. LAD lesions showed the highest mismatch. Angiographic or QCA estimation of lesion severity has consistently resulted in inappropriate stenting of functionally nonsignificant lesions or undertreatment of significant lesions based on FFR.

Abstract
Data regarding thrombolytic treatment of right-sided mechanical valve thrombosis are almost nonexistent, and all current guidelines arise from very small case series. We retrospectively studied the in-hospital and long-term outcome data of a larger series of patients who had received, from September 2005 through June 2012, thrombolytic therapy for right-sided mechanical pulmonary valve or tricuspid valve thrombosis. We identified 16 patients aged 8-67 years who had undergone thrombolytic therapy for definite thrombotic mechanical valve obstruction in the tricuspid or pulmonary valve position (8 in each position). All study patients except one had subtherapeutic international normalized ratios. The 8 patients with pulmonary mechanical valve thrombosis had a 100% response rate to thrombolytic therapy, and their in-hospital survival rate was also 100%. The 8 patients with tricuspid mechanical valve thrombosis had a 75% response rate to thrombolytic therapy, with an in-hospital survival rate of 87.5%. The one-year survival rate for mechanical valve thrombosis treated with thrombolytic therapy (whether pulmonary or tricuspid) was 87.5%. On the basis of our data, we recommend that thrombolytic therapy remain the first-line therapy for right-sided mechanical valve thrombosis in adults or children-including children with complex congenital heart disease and patients with mechanical pulmonary valve thrombosis. Surgery should be reserved for patients in whom this treatment fails.

Abstract
Myocardial fractional flow reserve (FFR) is a new index of the functional significance of intermediate coronary stenoses that is calculated from pressure measurements made during coronary arteriography. The aim of this study was to evaluate the correlation between non-hyperemic coronary pressure dicrotic notch and fractional flow reserve (FFR). A consecutive of 114 patients (73 men and 41 women) was enrolled in this study. Data were shown as means ± SD. Statistical analyses were performed with SPSS software. The statistical significance of differences was determined by chi-square analysis with Yates correction. Significance was defined as P< 0.05. Positive dicrortic notch was observed in 97 patients (85%). Significant association was detected between coronary pressure notch (dicrotic notch), and FFR as loss of the dicrotic notch was detected in 93.8% (15/16) of patients with FFR less than 0.75 (P=0.001). Upon ROC curve, a cutoff FFR value of approximately 0.75 demonstrated sensivity and specifity of 93.8% and 98%, respectively for loss of the dicrotic notch. The positive predictive value for loss of the dicrotic notch was 88.2%. Our study demonstrated loss of non-hyperemic coronary pressure diacrotic notch correlates significantly with FFR and may predict an FFR < 0.75 with high accuracy. In patients with functionally significant coronary stenosis, loss of non-hyperemic diacrotic notch appears to be a useful index of the functional severity of the stenoses and the need for coronary revascularization.

METHOD AND RESULTS The study was conducted on 72 patients in two centers. CTO angioplasty was done by the antegrade approach from the femoral and/or radial approach. The role of age, gender, anatomical variations such as calcification, length of the lesion, proximal bending, retrograde filling and occluded coronary artery (LAD, CCK or RCA), and wires were assessed. The success rate was 79.6%, and presence of calcification was an important factor in CTO PCI. Operator's experience, use of appropriate equipment and calcification are important factors in predicting a successful PCI.
